BARREL-HEATER.

To all whom it may concern:

Be it known that I, HENRY GRAHN, a citizen of the United States, residing in San Francisco, in the county of San Francisco and State of California, have invented a new and useful Improvement in a Barrel- Heater, of which the following is a specilication.

This invention relates to a device for heating and drying barrels, the heating of the barrel being done before the bottom of the barrel is placed in position.

The object of the invention is to heat a number of barrels at one time by means of an oil burner, and a further obj ect of the invention is to provide means by which the heated air is forced against the sides of the barrel, both inside and out.

With these objects in view the invention consists of the novel features of construction, hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which:

Figure 1 is a vertical longitudinal section. Fig. 2 is a transverse section on the line 2-2 vof Fig. 1. Fig. 3 is a transverse section through supporting beams.

In carrying out the invention, I construct a substantially horizontal flue, which may be built of brick in the form of an arched tunnel, as shown at 1. The upper inner wall of this ue slopes upwardlyv from front to rear, so that the rear end of the line is higher than the front end. The top of the flue is in ahorizontal plane, and preferably flush with the floor of the building in which the device is used, and this top forms a support for the barrels, while being heated, and is provided throughout its length with vertically arranged openings 4, which form vents for the escape of the heated air which travel adjacent the inclined wall 2, and passes through said vent to the supporting surface 3. The flue 1 is closed at its rear end, as indicated at 5 to prevent waste of the heated air, and may be provided with a door or removable front 6 through which passes the feed-pipe of any suitable form of oil burner. Below said burner an air space 8 is formed which communicates with the iiue by means of suitable air-passages 9, thereby providing the necessary draft.

Specification of Letters Patent.

Application filed June 24, 1909.

serial No. 504,123.

Arranged above the supporting surface 3 are supporting beams l0 carrying pulleys 11, over which run cables 12. Each cable is provided at one end with a counterweight 13, and at the opposite end with a hood 14, which opens downwardly, and which has a greater diameter than that of the barrel to be heated. Suspended centrally within each hood is a deflector l5, and each deflector is in vertical alinement with one of the vents 4.

In use the barrels are placed upon the supporting surface 3, so that one of the vents 4 opens centrally into each barrel, and the hoods are then lowered to within a short dis tance of the supporting surface, so that they cover or inclose the greater portion of the barrel. The heated air from the burner escapes through the vent 4 and striking the deflectors 15 is deiected toward the inner sides of the barrels and passing up through them into the upper portions of the hood descends upon the outside of the barrels, and escapes from around the lower edges of the hoods.

By using an oil burner, smoking of the barrels is avoided, and they can also be heated with less expense than by employing coal or wood for the purpose of heating air within a metal flue. By employing the counterweight, the hoods can be balanced so that they will hang in any position into which they may be moved.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a barrel heating device, a horizontal support having vents therein, means for feeding a current of hot air to said vents, hoods suspended over said vents, and deectors suspended in said hoods and in vertical alinement with the vents.

2. A device of the kind described comprising a substantially horizontal flue forming a barrel support and having vents in its upper side, an oil burner projecting into one end of the liue, means for admitting air to the flue beneath the burner, hoods adjustably suspended over the vents, and deflectors suspended within the hoods.
